JamesMoore, Chicago, Ill. Application May 12, 1943, Serial No. 486,705 (01. 72-438) 1 Claim.

This invention relates to new and useful improvements in devices for pressing mortar between bricks and other building elements in a which is hand operatedin practically an effortless manner.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 is a side'elevational view of the device.-

Figure 2 is a top plan view.

Figure 3 is a bottom plan view.

Figure 4 is a section taken substantially on the line 4-4 of Figure 3.

Figure 5 is a transverse sectional view taken substantially on the line 5-5 of Figure 4.

Figure 6 is a cross sectional view showing a slightly modified form of trough.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the device includes an elongated narrow trough consisting of closely spaced side walls 5, 6, a connecting end wall 7 and a removable top wall 8. Adjacent ends of the side walls 5, 6 and the top wall 8 overlap a block ll which has a pivot member extended from its upper outer corner and denoted by numeral ill and from which extends a tang H anchored ina handle i2. The pivot member i8 is laterally offset with respect to the trough, as at Ha, so that the handle I2 becomes located on a line spacially parallel to the trough 6.

A rocker l3 has a slotted portion receiving the pivot member in and fulcrumed to the latter by a pin l4, one end of this rocker being formed to provide a forefinger grip 15 while the, other end is offset in the direction of the offset lid and extends in a long sweeping arcuate portion iii to pass over the intermediate portion of the aforementioned trough.

Small teats I l, l8 on the block 9 and rocker l3 are embraced by the end convolutions of a coiled compression spring 19 which, of course, serves to maintain the free end of the portion IE of the rocker elevated.

Numeral 2'0 denotes an elongated plunger having suitable packing means 2! at the perimeter thereof. A stem 22 rises from the intermediate portion of the plunger 20 and extends through an openin 23 in the top plate 8. A pivotal link 24 connects the upper end of the stem 22 to the free end of the arcuate portion l6 of the rocker I3.

The end portions of the plunger 20 are provided with upstanding racks 25 which mesh with gears 26 located on shaft 21 that is supported by brackets 21a projecting from the wall 5. Obviously, theracks 25 and gears 26 serve to maintain the plunger 20 operating on an even plane.

It can be seen, that the spring I9 serves to maintain the plunger 20 elevated in the box structure so that the box structure can be readily filled with mortar, after which the box is placed against the work, where the joint is to be formed and the finger hook l5 pulled, this overcoming the spring IS with the result that the plunger 2n forces the mortar out of the box and into the space to be filled in the work.

Figure 6 discloses a slightly modified form of the invention, wherein the side walls 5a, 6a have grooved edge portions 35, 35 in which a cover 8a is slidable. This is a modification of the screw held cover 8 depicted in Figures 1 and 2.

gated narrow and shallow trough open at the bottom and consisting of spaced side walls, end walls and a removable top wall, one end wall embodying a. block overlapped by the side and top walls and secured to the side walls, said block having an upwardly and outwardly projecting pivot member and a tang projecting outwardly from said pivot member, an elongated handle secured on said tang, said pivot member and said tang being offset laterally relative to the trough, a rocker having a slotted portion receiving the pivot member and fulcrumed to the latter, the

outer end of the rocker being formed to provide a forefinger grip, a plunger slidable in the trough and having a rigid stem intermediate its ends slidable through the top wall of the trough and connected to the other end of the rocker, and a spring acting on the rocker to normally retract the plunger, said other end of the rocker extending laterally from the slotted portion to a point above the trough in line with said stem,
